Optionally, a body surface temperature of the user is detected by an infrared thermal sensing device to determine whether the user is in a dressed state. In this way, the body surface temperature of the user can be reduced under the shielding of clothes, so that the temperature detected by the infrared thermal sensing device when the user is in an undressed state is higher than the temperature detected when the user is in the dressed state, and whether the user is in the dressed state can be judged more accurately by temperature sensing.

Optionally, when the body surface temperature of the user exceeds a set temperature value, the user is judged to be in an undressed state. In this way, the temperature detected by the infrared thermal sensing device being higher than a set temperature value indicates that the user is in the undressed state, and whether the user is in a dressed state can be judged more accurately.

Optionally, a length of the bar-shaped sensing panel corresponds to a height of the air outlet in a proportion. In this way, the air outlet with the corresponding height can be conveniently controlled by the user according to a length of gesture sliding on the bar-shaped sensing panel, so that the control precision is improved, and the demand of the user is better met. For example, the length of the bar-shaped sensing panel is 20 cm, the height of the air outlet is 2 m, and 1 cm of sliding on the bar-shaped sensing panel corresponds to the opening of the air outlet for 0.1 m.
